Question

Describe how the scale illusion and mistetious melody task relate to Gestalt's laws of visual object perception in terms of grouping, segregation, and familiarity.

Answer 1

Gestalt psychologists searched for rules by which the brain organizes fragments of sensory data into gestalts (from the German word for "whole"), or meaningful forms. In pointing out that the whole may exceed the sum of its parts, they noted that we filter sensory information and construct our perceptions.
To recognize an object, we must first perceive it (see it as a figure) as distinct from its surroundings (the ground). We bring order and form to stimuli by organizing them into meaningful groups, following such rules as proximity, continuity, and closure.Depth perception is our ability to see objects in three dimensions and judge distance. The visual cliff and other research demonstrate that many species perceive the world in three dimensions at, or very soon after, birth.
Binocular cues, such as retinal disparity, are depth cues that rely on information from both eyes.
Monocular cues (such as relative size, interposition, relative height, relative motion, linear perspective, and light and shadow) let us judge depth using information transmitted by only one eye.
As objects move, we assume that shrinking objects are retreating and enlarging objects are approaching.
A quick succession of images on the retina can create an illusion of movement, as in stroboscopic movement or the phi phenomenon.
